Multiplexing of communications services on a virtual service path in an ATM network or the like

摘要

An asynchronous transfer mode (ATM) network or the like having a plurality of switches which may each be coupled with a central service provider over a virtual service path. Service requests, grants of service, and other control information for the network may then be communicated between each of said switches and the central service provider over virtual communication channels within said virtual service path. The disclosed method and apparatus provides for efficient communication of service requests and service grants without requirement to establish new communications paths between the individual switches and the central service provider for each request. Further, the ATM network may be managed by the central service provider as a logical star network.
